Earlier this month, Prime Minister Boris Johnson declared that the ban on the sale of petrol, diesel and hybrid cars is to be brought forward by 5 years to 20351. Although a positive move for the environment, it has brought concern to the industry about how this change will affect the national power grid as the sale of electric cars increases. Read more
Bandweaver, leading provider of fiber optic monitoring sensors and integrated technologies, is proud to be attending Elecrama. They will be attending in support of their key regional partner, Power International from 18-22 January 2020. Bandweaver’s Managing Director, Richard Kluth will be at the event on stand H4A7 alongside the Power International team, taking place at India Expo Mart, NCR India.
Bandweaver’s Dynamic Cable Rating (DCR) technology enables Scottish Power Energy Networks (SPEN) to utilise Distributed Temperature Sensing (DTS) system using real-time and historical data comparisons to increase wind farm capacity by 20% and enable cable rating enhancements of 25-35%.
Real Time Thermal Rating (RTTR) systems and distributed temperature sensing (DTS) technologies have been used within power cable condition monitoring to rate cables since the 1990’s. A well documented power cable failure in Auckland 1998 shut down the city’s central business district. As a result, this recognised the benefits of incorporating DTS and RTTR into power transmission operations.

Distributed Acoustic Sensing and Distributed Temperature Sensing are fiber optic sensing solutions. These measure temperature along the fiber either utilizing a technique called Coherent Optical Time Domain Reflectometry (COTDR) or Optical Time Domain Reflectometry (OTDR). Therefore, turning the entire length of a fiber optic cable into a sensor.

Bandweaver offer a range of distributed cable monitoring solutions, including fiber optic distributed temperature sensing (DTS) and distributed acoustic sensing (DAS) technology. These are a fundamental and essential tool for condition monitoring for transmission and distribution networks. With an increase in the demand for renewable energy schemes, often off-shore, there are major costs associated with asset management. These are due to the installation and maintenance of subsea cables which is both problematic and very expensive.

The Bandweaver RTTR system is used in conjunction with Distributed Temperature Sensing systems and used to protect five separate circuits. The circuit ratings vary from 33kV to 220kV and are a combination of copper core and aluminium cables. The data from the RTTR system will be exported to a Siemens’ SCADA system. The project was supplied in partnership with Alquist and Sensornet.
